Yes. Absolutely. Extreme professionals.
The US Army medevac unit rotated part-way through my second tour. They seemed pretty good. Their replacements seemed to do their job alright, but were extremely lousy with communications back to us in the TFK J3 Avn cell so we never knew when they had launched, arrived, or returned (and to the right places) without constantly nagging them.
They flew the cas in an unarmed Black Hawk with red crosses escorted by an Apache.
Pedros had no extra markings except for black moustaches on their noses and provided their own escort between the two GAU-21-armed Pave Hawks. Their primary mission was Combat SAR.
Look for that National Geographic DVD set. It's worth it.
There is no room for cas, Med Tech, and equipment in an armed Griffon. It's too small, and lacks the power to take off in an enemy-infested environment.
And red crosses don't impress many of the people that we are likely to fight.
